Creating the Author class
An Author is any possible source of an article, such as a news service or columnist. To create the Author class:
  1. Highlight the class :THING. If you do not do this, you will create a class that is a subclass of Columnist.

  2. Click the Create Class button and type Author.

  3. Hit Enter to complete and display your change.



    Note: If you accidentally create a subclass of Columnist, you forgot to select :THING before you created the class. You can delete and recreate the Author class by clicking the Delete Class button (fourth from the left, at the top of the Class Hierarchy area) to delete the class, and then clicking on :THING and creating another class. You can also rearrange the class hierarchy by dragging the class you created over :THING and then releasing the mouse button.
